Daily Miracle Sudoku
The extra rule
No repeat a king's move or knight's move away, and no consecutive neighbours.
Three rules at once. No digit repeats a king's move away. None repeats a knight's move away. And no two cells touching edge to edge hold consecutive digits.
The combination is so restrictive that a handful of digits pins the whole grid. That is where the name comes from: the original, set by Mitchell Lee in 2020, began with just two digits.
Fair warning that the constraints leave very few grids possible, so the underlying pattern repeats more than it does in the other variants here.
Controls
Click a cell and type a digit, or use the pad. Space toggles pencil marks. Arrow keys move. Progress saves in this browser as you go, so you can come back to the same puzzle later today.
Solvable Without Guessing
Every puzzle here was generated and then handed to a solver that is only allowed techniques a person can use. If it could not finish the grid without a guess, the puzzle was thrown away rather than published. That also makes the answer unique, because every digit it placed was forced.
